In our work the presence of the various sonographic signs
has an incidence similar to the data in the literature . Air bronchograms, due to the presence of trapped air in an airway, were identified in 92.8%. Fluid bronchograms were found in 28.5%, a high percentage due to the fact
that in pediatric age postobstructive pneumonia is frequent, while the superficial fluid
alveolograms were found in 75.0%.
